A circuit breaker, also known as an automatic switch, is an electrical appliance that has both manual switching functions and automatic voltage loss, undervoltage, overload, and short circuit protection. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power supply lines and motors, etc., and automatically cut off the circuit when they have serious overload or short-circuit and under-voltage faults. Its function is equivalent to a fuse switch and A combination of overheating and underheating relays, etc. Moreover, it is generally not necessary to change the parts after breaking the fault current, and it has been widely used at present.
